The paper investigates the distribution of Danube riverine water and formation of the water hydrological structure, the plume and buoyancy current response to various types of wind forcing on the North-Western shelf of the Black Sea using numerical modeling and satellite data analysis. Numerical experiments were conducted for a 3-dimensional ?-coordinate model, adapted to the North-Western shelf conditions, taking into account the bottom topography of the computational area and the actual configuration of the coastline. Wind impact scenarios for numerical experiments were formed using the assessment of winds different directions recurrence at the North-Western shelf and in the area of the Danube delta according to the ERA-Interim reanalysis. As a result, patterns of formation and evolution of the discharge thermohaline front and buoyancy current depending on the wind forcing of different directions were revealed. Comparison of calculations with satellite maps for upward radiation at a wavelength of 551 nm confirms the simulation results.
